  • Challenges in processing nickel laterite ores by flotation

    2016-6-6 · Flotation has not been successful in recovering nickel from laterite ores as the nickel is often finely disseminated in various minerals at a very fine size. Ultrafine grinding has to be used to liberate nickel-containing particles but the resultant fine particles means that recovery is low in conventional flotation cells.

    The separation selectivity and efficiency of the flotation depends not only on differences in the physico-chemical surface properties of different minerals within an ore but also on the hydrodynamics of flotation. The hydrodynamics influences many sub-processes of the flotation such as the suspension of particles in the pulp the dispersion of the air into bubbles and the probability of particle–bubble collision. Mechanical entrainment plays a major role in the quality of the flotation
